Core tip: Anorectal emergencies refer to anorectal disorders presenting with acute symptoms and signs which might require an immediate management. Anorectal emergencies usually include acutely thrombosed external hemorrhoid, complicated internal hemorrhoid, anal fissure, irreducible rectal prolapse, anorectal sepsis, sexually transmitted proctitis, obstructing rectal cancer and early complications after anorectal procedures. A detailed history taking, careful physical examination including digital rectal examination and anoscopy, and some radiological imaging are essential for correct diagnosis and plan of treatment. Clinicians should be familiar with these conditions especially anorectal sepsis which could be potentially lethal if delay in diagnosis and management.
